This afternoon comScore released December marketshare data for US smartphones. Android continued its march toward 50 percent penetration, while Apple also gained. All others declined. According to the data, Samsung is the top smartphone OEM.

The company also said that 40 percent of the US adult population owned smartphones as of December. This number is quite a bit lower than Nielsen’s 46 percent figure. Others have offered comparable estimates (e.g., Yankee Group). Indeed, the comScore number probably underestimates the number of smartphones in the US market.

The company also released data that showed apps and mobile browser usage neck and neck. Last month apps edged the browser for the first time.

IDC recently presented estimates and data about global OEM share (all handsets). Nokia was still the global leader followed by Samsung and then Apple, which showed the highest percentage growth (driven by the success of the iPhone 4S). Both Nokia and Samsung sell feature phones as well as smartphones.
